First of all - great with the item field group conditions, here are a few notes:
When using a dropdown list as a condition instead of a radiobutton list the new content is only rendered after you save the item, close it and reopen it. (I'll just use radio buttons for now ofc.)
Could we have the type "File" added to conditional statement - as in is one selected?
Would also love to be check for more than "==" & "!=" - fx Contains and > < would be much appreciated :)
Cya tomorrow ;)
